As a nursing practice involves nurses'actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives. Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal); excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, accountability and commitment(4 theories of nursing ethics); human respect, partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences, positive perspectives(4 theories of nurse), role of intervention, rewarding, peer relationship(3 theories of situations). The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore, it is recommended to review the theories-in-use in order to find any discrepancies between the espoused theories and the reality of nursing actions.

Background: Cigarette smoking is one of the leading causes of death in the world. Tobacco consumption has grave negative consequences for health so that it is important to understand the reasons and motivations towards cigarette smoking and barriers against quitting smoking among the young generation for developing effective policies to control this widespread problem. Materials and Methods: This cross-sectional survey was carried out at the Faculty of Medicine, Rabigh, King Abdulaziz University, Jeddah, Saudi Arabia. A total of 438 young smokers participated from the University and the general population. Data were collected through anonymous, self-administered questionnaires in the Arabic language that contained questions about the reasons and motivations towards cigarette smoking and barriers against quitting smoking. The questionnaire also contained several questions regarding knowledge and attitude of the participants towards cigarette smoking. The data was analyzed on SPSS-16. Results: The mean age of the respondents was $22.9{\pm}3.48$, out of 438 subjects 87 (19.9%) were married, and 351 (80.1%) were unmarried, and 331 (75.6%) belonged to urban areas while 107 (24.5%) were from the rural areas. Responding to a question about a number of cigarettes smoked per day, 31% answered 11-20, 29% answered 21-30, and 25% answered 1-10. Questioned about smokers in the family, 34.5% responded more than one, with 19% for brother and 13% for father. About the reasons for not quitting smoking, 26% described lack of willpower, 25% had no reason, 22% said that people around me smoke, and 15.3% responded stress at home/work. The major motivation for smokers was smoker friends (42%), for 33.8% others, for 12% father/brother and 7.8% media. Conclusions: There are several avoidable and preventable reasons and barriers against quitting smoking. However, knowledge and attitude about smoking were good, and the majority of the smokers were well aware of the associated hazards. Therefore, there is a need to search out ways and means to help them to quit this addiction.

This study provides numerical data on the status of music therapy practices in 54 hospice and palliative care settings in Korea. Two different questionnaires for music therapists and coordinators were sent to 54 coordinators via email, and 47 (87%) hospitals and centers replied by email or post. The survey period was October 30 through December 5, 2014. Music therapists were asked to respond to 65 questionnaire items regarding working conditions, environment, session process, and personal competence. Coordinators were asked to complete 28 questionnaire items regarding the status of music therapy in their perspective setting. Twenty-two (46.8%) hospitals and centers were running music therapy programs with 28 music therapists, and 19 (67.9%) of these music therapists majored in music therapy. There was a significant difference between music therapists (M= 3.43, SD = 0.96) and coordinators (M= 2.73, SD = 0.77) regarding conditions and environment of music therapy sessions (p < .05). The circumstances and conditions for music therapy are inad quate for optimal implementation of music therapy practice. However, the perceived benefits of music therapy by coordinators suggest that music therapists do play an important role in hospice and palliative care. This research provides the first quantitative baseline data of music therapy status in hospice and palliative care settings in Korea.

Therefore, their turnover can have a great influence on the company performance. The purpose of this study is to investigate the structural relationship between salespeople's personal - environmental fit and organizational commitment and turnover intention. Research design, data, and methodology - Data collection was conducted a self-filling questionnaire for salespeople for about one month from July 24, 2017 to August 30, 2017. The subjects of the questionnaire were the insurance salespeople who work in the sales line such as K life, S fire. A total of 450 copies were distributed and 432 copies of the questionnaire were used for final analysis. The analysis program used SPSS 22.0 and AMOS 22.0 programs. Analysis method was Frequency Analysis, Reliability & Confirmatory Factor Analysis, Correlation Analysis and Structural Equation Model(SEM). Results - As a result of Hypothesis 1, Person-Supervisor Fit had significant influence only on Continuance Commitment. Person-Job Fit did not have a significant effect on Organizational Commitment. Person-Coworker Fit had a significant effect on Continuance Commitment and Affective Commitment. Person-Organization Fit had a significant impact on Affective Commitment. Therefore, only , , , , were adopted. As a result of Hypothesis 2, Continuance Commitment had a significant effect on turnover intention. Therefore, only was adopted. Conclusions - This study suggests that it is necessary to manage the human resources in the sales field through studies related to salespeople's extension of the research scope and salespeople's turnover intention. Based on the results of this study, the conclusion suggests some implications for the efficient human resources management of insurance companies in sales channels. It is expected that it will be helpful for the salespeople to find out what kind of Person-Environment Fit affects the organizational commitment and how to manage the organizational commitment among the three dimensions of organizational commitment to reduce turnover intention.

The purpose of this descriptive study was to identify the homecare needs of patients with cancer and to provide a basis of interventions. One hundred and two patients at one general hospital in Gyeongnam responded to a questionnaire developed on the basis of care needs perceived by nurses caring for hospitalized patients with cancer. The questionnaire was a Likert type 5 point scale with 56 items on five need categories ; 1) informational 2) physical care : 3) emotional care 4) socioeconomic care and 5) special care needs. Internal consistency of this questionnaire was Cronbach's $\alpha$＝.9101 for total items. The data was collected from March 1st to May 31th, 1998, by two graduate nurses. In the data analysis, mean & standard deviation were calculated to identify the degree of care need of each item, and the t-test & ANOVA were done to determine the effects of patients' demographic background on their care needs. The findings are summarized as follows ; 1) The mean score of total of need items was 3.048. Of the four need categories the highest score was informational at 3.4, followed by emotional care, 3.063, physical care, 2.623, and socioeconomic care, 2.599. 2) In the informational need category there were four subcategories with 19 items. Medication and pain control had the highest score, 3.755 ; second was diet and exercise, 3.613 ; third was disease and treatment process, 3.337 ; and last was personal hygiene and infection prevention at 2.687. 3) In the physical care need category there was nine items, IV infusion for nutrition and management of treatment complication was above 3.2 points and the remaining items were in the 2.847-2.070 score ranges. 4) In the emotional care need category there were seven items. The highest need was in support for relationships with health personnel, 3.673. The need for support of religions beliefs and support for having a religion were low at about 2 points. 5) In the socioeconomic care need category there were six items. Support for medical insurance expansion and financial support were above 3 points. Legal support and support for caring of children were low in the care needs. 6) In the special care need category the there were 15 items. Informational need about immunization and informational need about effects of disease on growth and development were high, above 4.1 points. Need for decubitus care and prevention, sitz bath and incontinence care were low, below 2 points. 7) There were significant differences in degree of care need according to admission rate, education level, marital status, religion and caregiver's religion. In conclusion, homecare needs perceived by hospitalized patient's with cancer was moderate, but informational need was higher than direct care need, leading to the conclusion that the provision of sufficient information to patients with cancer at discharge is needed. Nursing interventions should be developed considering the patient's background.

Digital Radiography is a big part of diagnostic radiology. Because uncorrected digital radiography image supported false effect of Patient's health care. We must be manage the correct digital radiography image. Thus, the artifact images can have effect to make a wrong diagnosis. We report types of occurrence by analyzing the artifacts that occurs in digital radiography system. We had collected the artifacts occurred in digital radiography system of general hospital from 2007 to 2014. The collected data had analyzed and then had categorize as the occurred causes. The artifacts could be categorized by hardware artifacts, software artifacts, operating errors, system artifacts, and others. Hardware artifact from a Ghost artifact that is caused by lag effect occurred most frequently. The others cases are the artifacts caused by RF noise and foreign body in equipments. Software artifacts are many different types of reasons. The uncorrected processing artifacts and the image processing error artifacts occurred most frequently. Exposure data recognize (EDR) error artifacts, the processing error of commissural line, and etc., the software artifacts were caused by various reasons. Operating artifacts were caused when the user didn't have the full understanding of the digital medical image system. System artifacts had appeared the error due to DICOM header information and the compression algorithm. The obvious artifacts should be re-examined, and it could result in increasing the exposure dose of the patient. The unclear artifact leads to a wrong diagnosis and added examination. The ability to correctly determine artifact are required. We have to reduce the artifact occurrences by understanding its characteristic and providing sustainable education as well as the maintenance of the equipments.

The purpose of this study was to provide the valid data about residential-linked pension insurance development. The development was a part of national housing projects, which was an incentive for rural living of retired people, in order to relieve residential issues of elderly and revitalize rural communities by residents moving from cities. The insuring intent, decisive insuring factors and the residential service demand degree of people preparing retirement were analyzed. Data was collected in October, 2007. 364 Sample Subjects lived in Seoul Metropolitan area. Firstly, more than 90% of respondents had intention to purchase a residential-linked pension insurance and about 50% of them necessarily desired receiving premium for moving in. This indicated that it could be developed as an insurance which helped to meet housing expenses by housing-linked system, and in the mean time, it met the original purpose of pension insurance as the pension benefit could be guaranteed for all the insurance subscribers. Secondly, the respondents, whose income and private assets were higher, were able to pay more for insurance compared to average. Therefore, It was necessary to regulate monthly insurance bill and the payment period according to asset states of insurance subscribers after establishing certain amount of total insurance payment. Thirdly, by and large, it indicated the tendency that the less they prepare for older age the later they wanted to move into the pension insurance residence. It was inferred that in the case of insufficient preparation for older age, people preferred preparing behind time by postponing move in to moving in early to enjoy retired life, due to uncertainties. lastly, the respondents understood the significance of health, medical treatment and emergency management service and these two services were preferred as essential provided services. Because of the necessity of developing residential-linked pension insurance was found to be positive, further research to find the real cost, directives for operation and institutional support for this type of pension insurance might be needed.

The maintenance of a viable pregnancy has long been viewed as an immunological paradox. The deveolping embryo and trophoblast are immunologically foreign to the maternal immune system due to their maternally inherited genes products and tissue-specific differentiation antigens (Hill & Anderson, 1988). Therefore, speculation has arisen that spontaneous abortion may be caused by impaired maternal immune tolerance to the semiallogenic conceptus (Hill, 1990). Loss of recall antigen has been reported in immunosuppressed transplant recipients and is associated with graft survival (Muluk et al., 1991; Schulik et al., 1994). Progesterone $(10^{-5}M)$ has immunosuppressive capabilities (Szekeres-Bartho et al., 1985). Previous study showed that fertile women, but not women with unexplained recurrent abortion (URA), lose their immune response to recall antigens when pregnant (Bermas & Hill, 1997). Therefore, we hypothesized that immunosuppressive doses of progesterone may affect proliferative response of lymphocytes to trophoblast antigen and alloantigen. Proliferative responses using $^3H$-thymidine ($^3H$-TdR) incorporation of peripheral blood mononuclear cells (PBMCs) to the irradiated allogeneic periperal blood mononuclear cells as alloantigen, trophoblast extract and Flu as recall antigen, and PHA as mitogen were serially checked in 9 women who had experienced unexplained recurrent miscarriage. Progesterone vaginal suppositories (100mg b.i.d; Utrogestan, Organon) beginning 3 days after ovulation were given to 9 women with unexplained RSA who had prior evidence of Th1 immunity to trophoblast. We checked proliferation responses to conception cycle before and after progesterone supplementation once a week through the first 7 weeks of pregnancy. All patients of alloantigen and PHA had a positive proliferation response that occmed in the baseline phase. But 4 out of 9 patients (44.4%) of trophoblast antigen and Flu antigen had a positive proliferative response. The suppression of proliferation response to each antigen were started after proliferative phase and during pregnancy cycles. Our data demonstrated that since in vivo progesterone treated PBMCs suppressed more T-lymphocyte activation and $^3H$-TdR incorporation compare to PBMCs, which are not influenced by progesterone. This data suggested that it might be influenced by immunosuppressive effect of progesterone. In conclusion, progesterone may play an important immunological role in regulating local immune response in the fetal-placental unit. Furthermore, in the 9 women given progesterone during a conception cycle, Only two (22%) repeat pregnancy losses occured in these 9 women despite loss of antigen responsiveness (one chemical pregnancy loss and one loss at 8 weeks of growth which was karyotyped as a Trisomy 4). These finding suggested that pregnancy loss due to fetal aneuploidy is not associated with immunological phenomena.

The WBAN technology means a short distance wireless network which provides each device interactive communication by connecting devices inside and outside of body. Standardization on the physical layer, data link layer, network layer and application layer is in progress by IEEE 802.15.6 TG BAN. Wireless body area network is usually configured in energy efficient using sensor and zigbee device due to the power limitation and the characteristics of human body. Wireless sensor network consist of sensor field and sink node. Sensor field are composed a lot of sensor node and sink node collect sensing data. Wireless sensor network has capacity of the self constitution by protocol where placed in large area without fixed position. In this paper, we proposed the efficient addressing scheme for improving the performance of routing algorithm by using ZigBee in WBAN environment. A distributed address allocation scheme used an existing algorithm that has wasted in address space. Therefore proposing x, y and z coordinate axes from divided address space of 16 bit to solve this problems. Each node was reduced not only bitwise but also multi hop using the coordinate axes while routing than Cskip algorithm. I compared the performance between the standard and the proposed mechanism through the numerical analysis. Simulation verified performance about decrease averaging multi hop count that compare proposing algorithm and another. The numerical analysis results show that proposed algorithm reduced the multi hop better than ZigBee distributed address assignment

Objectives : To investigate the applicability of thermography as severity measurement in the patients with osteoarthritis (OA) of the knee. Methods : Data were obtained from 80 patiens with OA of the knee. They were asked to answer two disease-specific questionnaire (Western Ontario and McMaster Universities (WOMAC) OA index. Lequesne's Functional Index (LFI)), one generic instrument (Korean Health Assessment Questionnaire (KHAQ)), VAS in order to assess the severity of disease, quality of life, and degree of pain and taken thermography in standardized environment. Results : The thermal difference between ipsilateral side and contralaterla side of lateral aspect of knee was correlated with that of medial aspect of knee, and the thermal difference of anterior thigh was correlated with that of lateral, medial aspect of knee and patella region. Age, duration of disease, duration of morning stiffness, sex, crepitus, and painful side of knee were not correlated with the thermal differences of each region. LFI, WOMAC, WOMAC pain subscale, WOMAC stiffness subscale, WOMAC physical function, KHAQ, VAS were not correlated with the thermal differences of each region. Conclusion : Futher study on the thermography on OA of the knee in population with appropriate severity grade and the standardization of analysis of thermographic data were recommended.
